ABSTRACT:
An apparatus and method for treating waste products produced by chemical processing plants. Steam stripping waste sour water results in a vapor including ammonia and hydrogen sulfide. A scrubber unit including a quenching column produces a concentrated ammonium sulfide solution. The concentrated ammonium sulfide allows for more efficient transfer from more than one refinery to a centralized purification facility for further processing.
